WILLIAM M. GOLDSMITH, OF CINCINNATI, OHIO.-

SASH CONSTRUCTION.

Specification of Letters Patent.

Patented Oct. 1'2, 1911-;

Application filed May 10, 1911. Serial No. 626,379. 1

To all whom it may concern:

Be it known that I, IVILLIAM M. GOLD SMITH, va citizen of the UnitedStates of Another object of my invention is a s ash construction, thesteps of manufacture and assembling of which are inexpensive.

These and other objects I attain by the means described. in thespecification, and

illustrated in the accompanying drawings, in which,

Figure 1 is a part of a sash illustrative of the construction embodyingmy invention. Figs. 2 and 3 are perspective views of the intersectingmembers of which the sash is composed, the parts being shown on somewhatan enlarged scale. Fig. 4 is a perspective view of the parts shown inFigs. 2. and

- 3, in the position they occupy relatively to each other when assembledin a sash.

The sash construction embodying my 111- vention consists of horizontaland vertical interlocking T-bars, which, at the points oi intersection,have the flange of one-of the intersecting T-bars cut away to pass theflange of'its intersecting bar, and have the web of said intersectingbar slottedto pass the web of the first bar.

In the accompanying drawings, I have shown the flanges of the horizontalmembers as being cut away at intervals, and the webs of theverticalmembers as being slotted, but I may reverse this order and cutthe flanges of the vertical memberscand the webs of the horizontal ones.The flanges a of the horizontal members have a part removed, which is ofthe Width of the flange Z) of the vertical members, the sides a a of thecut in the flange, a, being parallel, so as to fit snugly againstthe-sides of the flange b. In the web of the horizontal member, midwaybetween the sideso a of the cut, there is formed a notch a The web 6-"of the vertical members have in them a slot 6 of a width equal to thewidth of the Web a of the-horizontal members. so that the sides of theslots 6 side of the slot 6 is a tooth b, which, in. the assembledposition of the T-bars, fits into the notch a The tooth b and the notcha have their upper edges at equal distances from the flanges a and b, sothat when the slot 6 is passed over the flange a, the tooth fit thesides of the web a snugly. Upon the b will be sprung into the notch-abyythe 1 elasticity ofthielmetal, at the time when the flanges a and I)become flush with each other in fitting the bars together. Y

The cut away portions of the'flanges of the horizontal members are madeat a distance apart, equal to the width of the pane of the sash, and theslots 6? of the webs of the vertical members are at a distance apart,equal to the height of the pane of the sash.

The manufacturer may-ship the T-bars to the building, in which thesashes are to be installed, unassembled. To assemble them, the workmansimply has to bring the slotted portion ofthe webs of the verticalmembers to register with the webs at thecut away portions of thehorizontal members, and

then to drive the vertical members to place 1 upon the horizontalmembers, so that the teeth b fit into the notches a In this position,the flanges of the T-bars are flush with each other, and together withthe webs form a framework into which the panes of glass may be seated.

lVhat I claim is 1. A sash construction consisting of T-.

'bars crossing each other, each of said T-bars consisting of a flatflange having parallel faces and parallel edges, and an integral web atright angles to the flange, one of the T-bars at the point ofintersection having its flangecut out, the cut-out portion being of thewidth of the flange of the" second T- bar, the second T-bar having itsweb cut out, the cut-out portion of the web being of the width of thethickness of the web of the first T-bar, the bars being assembled withthe .web of one embracing the web of the other and with their flangesflush with each other, and a means for lockingthe T-bars together formedby a notch in the uncut web and a tooth upon the'slotted edge of theother web and fitting into the notch.

2. A sash construction consisting of T- bars crossing each other, eachof said T- bars consisting of a flat flange having parallel facesandparallel edges, and an 1ntegral web at right angles to. the flange,oneof the T-bars at the point of intersection having its flange cut out,thecut-out porwith each other, and a means connecting tion being of thewidth of the flange of the webs of the T-baers together, said means 10the second T-bar, the second T-bar having being integral with the Webs.its web cut out, the cut-out portion of the a web being of the width ofthe thickness of WILLIAM GOLDSMITH- the'web of the first T-bar, the barsbeing Witnesses:

assembled with the Web of one embracing the WALTER F. MURRAY,

web-0f the other and with their flanges flush MAX S. GOLDSMITH.
